        </asp:TemplateField>
    </Columns>
</asp:GridView>要获取cc1:Calendar 控件的值。cc1:Calendar 是自定义控件

Answer 1

也就是cc1:Calendar 中的时间值。

Answer 2

看html源文件， 看看用document.getElementById("calStartTime ") 取到的是什么， 然后通过childNodes 取到值。 

Answer 3

document.getElementById("<%calStartTime.clientId %> ")试试

Answer 4

GridView 输出的还是table要想JavaScript操作，只要JavaScript能找到table节点对象，和原来操作没两样。楼主这不是HTML，这是ASPX的源码。JavaScript是不能在服务器端运行的，楼主看看GridView运行输出后的代码，再研究研究。
